Should I Hire an Agent to Rent my Apartment Building?

[Anthony Maicki]

My partners and I recently rehabbed a 12 unit apartment building on Chicago's Southwest side.  We have 12 beautiful one bed / one bath apartments with brand new appliances and individual energy efficient furnaces.  We have one of the nicest buildings in the area, and are also asking less than market rate.  However since it has been vacant for years coupled with  the time of year (January), I am wondering if it would be wiser to hire a real estate agent to rent the units out, or to do it myself?  I have signed the property up on Zillow, reached out to the 17th ward community, posted adds on craigslist, hit the streets with flyers, etc.  Please keep in mind that this is nice area, but a lower-income area.  There aren't many traditional real estate brokers working in the area.  Any insight on similar situations would be extremely helpful.
